Typically, the most expensive type of Christmas tree is either the Douglas fir or the fraser fir. That being said, lots of different factors can affect what you’ll pay for a Christmas tree including supply and demand, size of the tree, and more. Your best bet is to speak with a pro at your local Christmas tree farm to find the best tree for you.

It’s not a good idea to mix LED and incandescent Christmas lights if you can avoid it. LEDs and incandescents can have significantly different electrical current needs. This difference can lead to a higher risk of problems and failure for both light strands. When possible, switch all your lights over to one kind or the other for the best results. Do not connect the different types of light strings to each other, and avoid linking them to the same circuit. 

One of the easiest ways to save money when hiring a holiday decorator is to provide storage for your decorations. If you have the space, you can save hundreds or even thousands of dollars by avoiding storage costs through your professional. It’s also a good idea to provide as much direction as possible for your professional, as this can cut down on design services. Finally, you can pay for your decorator to take down your decorations at the end of the season, but packaging and storing them yourself will save money on labor.

No, you should not leave LED Christmas lights up all year. While the LED lights themselves are very durable, their wiring and casings can be as vulnerable as any Christmas lights. They’re subject to drying out, experiencing cold or sun damage that causes them to crack, and even damage caused by gnawing pests. (The same is true of incandescents.) If you want your lights to last the years that they’re rated for, bring them inside after Christmas is over.
